Q

What is Metabolism ?

A

Process in which the body transfers the drug into an inactive form so it can be excreted. Mostly occurs in liver (broken down into metabolites) and excreted from the body.

Q

What is excretion?

A

Elimination of drugs form the body. Mostly occurs in the kidneys but depending on the chemical make up; can be excreted via the intestines, lungs, breast milk or exocrine glands. A patient can have toxic effects from drug metabolism if they have impaired renal function or dehydration.

25
What is direct-binding agnostic?
Binds directly to the receptor sites and acts just like a neurotransmitter. It is a agnostic drug.
26
What is an indirect-acting agonist?
These cause more neurotransmitter to be released and thus enhance its action.
27
What is an example of an indirect-acting agonist in the dopamine system?
Cocaine
28
What is an antagonist?
It binds to the receptor in the brain but blocks other chemicals from causing a reaction.
29
Antagonistic drugs come in how many how many main forms?
2
30
What is a Direct-acting antagonist drug?
bind to the same receptor area as neurostransmitters and block the neurotransmitters themselves from binding to their receptors.
31
What is a antagonist indirect acting drug?
works by inhibiting the production or release of neurotransmitters.
32
What is an example of an antagonist and is an opiate antidote?
Narcan (Nalooxone)
33
Opioids include what?

34
When a person is overdosing on an opioid their breathing can?
Breathing can slow down or stop and it can very hard to wake them from this state.
35
Agonists
Drugs that occupy receptors and activate them.
36
Antagonists
Drugs that occupy receptors but do not activate them, antagonists block receptor activation by agonist.
37
How many medication effects are there?
6
38
Therapeutic effect
The action of drugs on a specific cell. Results in anticipated outcomes. When receptors and drugs lock together, a therapeutic effect occurs.
39
Side effect
An undesirable predictable action of a drug.
40
Toxic effect
Occurs when a drug is not adequately excreted. There is dangerous accumulation of the drug. May also occur from impaired metabolism, drug overdose or sensitivity.
41
Idiosyncratic effect
when a patient over reacts or under reacts to a | drug or has an unusual response.
42
What is an example of an Idiosyncratic effect?
a patient becomes agitated rather than sedate after | administration of phenobarbital.
43
Allergic response
Occurs after a patient has become sensitized to an initial dose of a medication. This is an allergic response to an allergen which is a substance to which a sensitivity has been established or a related drug.
44
Synergistic effect
Occurs when more than one drug is taken at the same time. The effect may go beyond the desired outcome.
45
What is an example of a synergistic effect?
Blood pressure medication and a diuretic taken together may cause a drastic decrease in BP.
46
Classification can be | By action, which means?
a grouping of drugs that have similar chemical action. Usually referred to as drug families. Not to be confused with drug cartels.
47
Classification can be | By legal classification which is?
Prescription | Non-prescription
48
Common families of drugs (See list in notes and page 251) | Analgesics
relieve pain and can be a narcotic or nonnarcotic
49
Antihistamines
treat allergic disorders, both acute and chronic
50
Coagulants
control hemorrhage or speed up coagulation. | Novoseven
51
Hypoglycemics
control the level of glucose in the blood
52
Vasodilators
cause blood vessels to dilate
53
Medication Administration | Indication
A reason to prescribe a medication or perform a treatment.
54
Medication Administration Contraindication
A factor that prohibits the administration of a drug or the | performance of an act or procedure in the care of a specific patient.
55
Administration of BaSO4contrast media.
Indication This test involves the oral ingestion of barium, a radio-opaque substance, in order to image the upper digestive tract. It is important to remember that the study highlights intraluminal anatomy.
56
If a patient had a stomach ulcer, then the BaSo4 would be contradicted, why?
In cases where barium is contradicted, a water soluble contrast media would be indicated as seen below.
57
What are the radiographer’s role pertaining to contrast media?
This is considered a medication. You may or may not be able to administer contrast media. This depends on state licensing and policy.
58
What are the supportive roles of the radiographer?
Prepare the necessary items needed for the procedure | To assess patient from the start of the procedure until the patient is discharged from the department.
59
How should you assess the patient from the start of the procedure until discharged?
Check allergy history Verify pt ID Assist radiologist or physician
60
What consist of a standing order?
* written directions for a specific medication or procedure * signed by a physician * used only under the specific conditions as stated in the order * most contrast studies will have standing orders that are protocol for all patients except those who may have a condition that contradicts the standing order
61
What is a dosage?
Range of acceptable for each medication • some are not approved for pediatrics • physicians might change the “normal” dose.
62
What are the forms of dosages?
Tablets/Capsules/Suspensions • Suppositories • skin patches
63

64
What is the most common form of an external route?
Oral
65
What is an inhalation route?

66
What is a tropical route?
Medication is applied to the surface of the skin.
67
Lotions are a what?
A local effect
68
What is a transdermal tropical route?
More involved. Applied to the skin in the form of a paste or patch. Medication is then absorbed into the bloodstream. (Systemic effect)
69
What is a Sublingual/Buccal route?
Drugs placed under the tongue or inside the cheek. Will be absorbed directly into the bloodstream.
70
What is a Parenteral route?
Medication is injected directly into the body. Produces a rapid response, avoids irritation to the GI tract.
71
What is a parenteral intradermal route?
between the layers of skin. (TB test)
72
What is Subcutaneous (subq./SC) parenteral route?
Injections to the fatty layer below the skin. (Insulin)
73
What is Intramuscular (IM) parenteral route?
Injections into larger denser muscles (Delts/Quads) (Flu)
74
What is a parental Intravascular route?
Generally into the vein sometimes into an artery. (Contrast)
75
What is a parental Intrathecal route?
Injected into the subarachnoid space of the spinal canal (myelograms)
76
What happens if the 6R’s are read?
These are very important rights. All must be followed completely. If any are missed or not verified completely, the patient could be affected by this and the hospital may be in jeopardy of a lawsuit.
77
Each time you administer a medication, you need to be sure to have the: 6 Rs of medication administration
1. Right individual 2. Right medication 3. Right dose 4. Right time 5. Right route 6. Right documentation
78
What are 2 general types of contrast media?
Radiolucent | Radiopaque
79
What do barium sulfate procedure go through?
Oral | Rectal
80
Negative Contrast Media Procedures
Air
81
Iodinated Contrast Media Procedures include?
Ionic Non ionic Reactions pre contrast history
82
Reactions
* Mild * Intermediate * Severe
83
What is Venipuncture?
The puncturing of a vein for the removal of blood or for the administration of fluids &/or drugs.
84
Sites of anatomic considerations for the antecubital space?
Cephalic vein Basilic vein Antecubital Vein (Medial Cubital)
85
What are the anatomical consideration sites for the posterior aspect of the hand?
* Cephalic vein | * Basilic vein
86
What is the first choice for venipuncture and why?
Median cubital vein because it is large, well anchored, least painful, and least likely to bruise.
87
What is the 2nd choice for venipuncture and what is its characteristics?
It is large, but not as well anchored and is more painful when when punctured than the median cubital.
88
What is the 3rd choice for venipuncture and what are its characteristics?
Easy to palpate, but not well anchored. It lies near the brachial artery and the median nerve, either of which could accidentally be punctured.
